Electrochemical performance of carbon-Nickel electrode with PVDF binderfor supercapacitor applications

In this study, a carbon electrode with nickel nanoparticles and Polyvinylidene fluoride (PVDF) as abinder was fabricated and its electrochemical properties were explored in KOH (Potassiumhydroxide) electrolyte for potential use in supercapacitor manufacturing. cyclic voltammetry (CV)analysis revealed that the carbon-nickel (C-Ni) electrode achieved a maximum specific capacitanceof ۱۸۸.۶۸ F/g at a scan rate of ۱۰ mV/s in a ۶ M KOH electrolyte. After ۱۰۰ cycles at a scan rate of۱۰۰ mV/s, the C-Ni electrode retained approximately ۹۶% of its initial capacitances, demonstratingexcellent electrochemical stability. This stability is attributed to the resistance of PVDF againstdegradation as a binder in the KOH electrolyte.
